高效离子交换色谱法分离稀土元素的工作近十年来国外已有报导,但需要昴贵的仪器和特殊的填料,我们使用国产仪器和填科,以HIBA为洗脱剂。用外梯度装置,采取浓度和PH并行变化的梯度形式,成功地在1小时内分离了十三个稀土元素,见图1。在分离度及分离时间方面与国外同类型仪器和填料相比,其结果尚为接近, Efficient ion exchange chromatography separation of rare earth elements work has been reported in foreign countries for nearly a decade, but the need for expensive instruments and special filler, we use domestic instruments and fill subjects to HIBA as eluent. Thirteen rare earth elements were successfully separated within 1 hour using an external gradient device in the form of a gradient of parallel changes in concentration and pH, see Figure 1. In terms of resolution and separation time with foreign similar instruments and packing, the results are still close,
